"Recently, after several months of saving, I bought an ASUS SABERTOOTH
990FX R2.0 Motherboard and an AMD FX-8350 Vishera CPU to go with it. As
you probably would imagine if you are reading this, I felt like a kid on
Christmas morning and was eager to get to using my new hardware. The
problem is that (at this moment) there is not any (official) way to use
a Piledriver CPU with this motherboard. You heard right. Not only does
ASUS' latest motherboard the SABERTOOTH 990FX R2.0, which features AMD's
newest enthusiast chipset, not support this CPU out of the box there is
currently not even a BIOS available from ASUS to support it, either."
